Abstract Background Population level data regarding the general mental health status, and the socio-demographic factors associated with the mental health status of adolescents in Australia aged 12–16 years is limited. This study assessed prevalence of mental health problems in a regional population of Australian students in Grades 7–10, and investigated associations between mental health problems and socio-demographic factors. Methods A web-based survey was conducted in 21 secondary schools located in disadvantaged local government areas in one regional local health district of NSW Australia. Mental health problems were measured using the youth self-report Strengths and Difficulties Questionnaire (SDQ) total SDQ score and three subscale scores (internalising problems, externalising problems and prosocial behaviour). Associations between each SDQ outcome and student socio-demographic characteristics (age, gender, Aboriginal and/or Torres Strait Islander Status, remoteness of residential location and socio-economic disadvantage) were investigated. Results Data are reported for 6793 students aged 12–16 years. Nineteen percent of participants scored in the 'very high' range for the total SDQ, 18.0 % for internalising problems, 11.3 % for externalising problems and 8.9 % for prosocial behaviour problems. Gender and Aboriginal status were associated with all four SDQ outcomes, while age was associated with two, excluding externalising problems and prosocial behaviour. Aboriginal adolescents scored higher for mental health problems than non-Aboriginal adolescents for all four SDQ outcomes. Females scored higher than males for total SDQ and internalising problems, with mean difference greatest at age 15. Males scored higher for externalising problems and lower for prosocial behaviour than females. Conclusions The finding that mental health problems significantly varied by age, gender and Aboriginality may suggest a need for tailored interventions for groups of adolescents with highest levels of mental health problems.

Objective: Individual and environmental resilience protective factors are suggested to be associated with adolescent condom use; however, previous studies have not comprehensively examined such associations. This study aimed to determine the associations between condom use, and numerous individual and environmental resilience protective factors in sexually active Australian adolescents. Methods: Participants were Grade 10 students attending 28 Australian government high schools (n=1,688). An online survey (2011) collected data regarding: sexual intercourse (past year), condom use and 14 individual and environmental resilience protective factors. Multivariable backward stepwise logistic regression models examined associations between student condom use and protective factors (total, subscale). Results: Only total environmental protective factors remained in the final total score model; students with higher total environmental protective factors scores were 2.59 times more likely to always use a condom(95%CI:1.80-3.74). Only three of 14 protective factor subscales were associated with a higher likelihood of always using a condom in the final subscale model (individual: goals/aspirations; environmental: community participation, pro-social peers). Conclusions: Total environmental and three protective factor subscales demonstrated prominent associations with consistent use of condoms in sexually active adolescents. Implications for public health: Consideration of particular resilience protective factors in adolescent sexual risk behaviour prevention, such as condom use, is warranted.

Background: Internationally, governments have implemented school-based nutrition policies to restrict the availability of unhealthy foods from sale. The aim of the trial was to assess the effectiveness of a multi-strategic intervention to increase implementation of a state-wide healthy canteen policy. The impact of the intervention on the energy, total fat, and sodium of children's canteen purchases and on schools' canteen revenue was also assessed. Methods: Australian primary schools with a canteen were randomised to receive a 12–14-month, multi-strategic intervention or to a no intervention control group. The intervention sought to increase implementation of a state-wide healthy canteen policy which required schools to remove unhealthy items (classified as 'red' or 'banned') from regular sale and encouraged schools to 'fill the menu' with healthy items (classified as 'green'). The intervention strategies included allocation of a support officer to assist with policy implementation, engagement of school principals and parent committees, consensus processes with canteen managers, training, provision of tools and resources, academic detailing, performance feedback, recognition and marketing initiatives. Data were collected at baseline (April to September, 2013) and at completion of the implementation period (November, 2014 to April, 2015). Results: Seventy schools participated in the trial. Relative to control, at follow-up, intervention schools were significantly more likely to have menus without 'red' or 'banned' items (RR = 21.11; 95% CI 3.30 to 147.28; p ≤ 0.01) and to have at least 50% of menu items classified as 'green' (RR = 3.06; 95% CI 1.64 to 5.68; p ≤ 0.01). At follow-up, student purchases from intervention school canteens were significantly lower in total fat (difference = −1.51 g; 95% CI −2.84 to −0.18; p = 0.028) compared to controls, but not in energy (difference = −132.32 kJ; 95% CI −280.99 to 16.34; p = 0.080) or sodium (difference = −46.81 mg; 95% CI −96.97 to 3.35; p = 0.067). Canteen revenue did not differ significantly between groups. Conclusion: Poor implementation of evidence-based school nutrition policies is a problem experienced by governments internationally, and one with significant implications for public health. The study makes an important contribution to the limited experimental evidence regarding strategies to improve implementation of school nutrition policies and suggests that, with multi-strategic support, implementation of healthy canteen policies can be achieved in most schools.
